Lime Shaft Kiln Production Line

Lime Shaft Kiln Production Line: Workingsite

A lime kiln is used to produce quicklime through the calcinations of limestone (calcium carbonate). The chemical equation for this reaction is

CaCO3 + heat→CaO + CO2

This reaction takes place at 900 °C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around 1000 °C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces un-reactive, "dead-burned" lime.

Lime Shaft Kiln Production Line: Coal and Limestone Feeding

Our company uses the most advanced calcium oxide vertical energy saving calcinations kiln, which combines a new lime kiln shaft kiln advanced production technology, a circular cross-section kiln structure, and the use of high-strength wear-resistant and thermal insulation properties good refractory masonry. Feeding materials and sealing device located at the top of the kiln. Discharge and sealing device located at the bottom of the kiln.

Lime Shaft Kiln Production Line: DCS Control System

The kiln filling mode using the original fuel mixture (the materials and hot air exchange reaction). It is also known counter-flow lime kiln. The kiln loading, discharging and operation are control by DCS centralized control system. It could control the process of shaft kiln firing batching, stable firing zone, discharging, air ventilation, others aspect of the calcinations and ensure that all finished products white color, high pulp production volume, high calcium, rarely less burnt fuel output. All of the operation is simple, one operator per shift can guarantee two lime kiln operation. It is not only greatly improve the labor productivity, and also ensure product quality and stability.
